Patent number: 11554270Abstract: It is provided a method for optimizing a treatment plan for use in radiation therapy. The method is performed in a treatment planning system and comprises the steps of: obtaining a first quality function of the treatment plan, the first quality function yielding an output value based on an input treatment plan; obtaining a first pair of input values and a slope indicator, the input values associating a value of the first quality function to a value of a score; constructing a score function that maps values of the first quality function to values of the score by fitting a curve to the first pair of input values and the slope indicator; and optimizing the treatment plan with respect to the score function, by varying the treatment plan such that the value of the score function is either improved or constrained to a feasible range of score values.Type: GrantFiled: June 12, 2018Date of Patent: January 17, 2023Assignee: RaySearch Laboratories ABInventors: Björn Andersson, Björn Hårdemark, Rasmus Bokrantz

Method comprising measurement on fuel channels of fuel assemblies for nuclear boiling water reactors
Patent number: 8699654Abstract: The invention concerns a method comprising measurement on a fuel channel (14) of fuel assemblies (8) for nuclear boiling water reactors. The method comprises that: the measurement is done by the use of a non-destructive inductive eddy current measurement method, the measurement is done on a fuel channel (14) which has been used at least a certain time during operation in the core of a nuclear boiling water reactor, the measurement is done when the fuel channel (14) is located in water, the measurement is done on different places on the fuel channel (14), wherein through the method at least the hydride content of the fuel channel (14) at said places is determined. The method can be used in order to find out how shadow corrosion from a neighboring control rod influences the properties of the fuel channel (14).Type: GrantFiled: June 8, 2009Date of Patent: April 15, 2014Assignee: Westinghouse Electric Sweden ABInventors: Kurt-Åke Magnusson, Holger Wiese, Björn Andersson, Göran Jergeus -

Patent number: 8117940Abstract: A steering wheel arrangement for a motor vehicle includes a steering column having a first end for cooperation with a steering wheel and a second end for cooperation with a vehicle steering mechanism. The steering wheel arrangement further includes a suspension arrangement for the steering column. The suspension arrangement includes two pivot joints and is pivotally connected to the steering column via a third pivot joint, the first, second and third pivot joints including first, second and third locking arrangements, respectively. The steering wheel arrangement has thus three adjustable pivot points where only one or two of the three pivot joints are adjustable in a first step depressing a foot pedal to a first position and only the remaining of the three pivot joints are adjustable in a second step depressing the foot pedal to a second position which implies that the adjustments can be made in a secure way by the driver during the ride.Type: GrantFiled: October 28, 2005Date of Patent: February 21, 2012Assignees: Volvo Lastvagnan AB, Fuji Autotech ABInventors: Björn Andersson, Hassan Omarain, Andreas Alvehav, Thomas Paulsson, Hans Fredriksson, Ulf Eriksson, Pentti Hyvönen

Patent number: 7085608Abstract: In a plant for controlling an equipment (4) adapted to carry out a process a superior arrangement (1) exists and has a first interface (2) to a programming unit (3) and a second interface (5) between the process equipment (4) and the arrangement. The arrangement has members (6) for transmitting information between the two interfaces. A memory member (9) adapted to store important data required for describing and defining the process of the process equipment is arranged in the process equipment itself. The arrangement (1) is provided with a rule data base (8) and a text data base (7) containing a configuration file for communication between the process equipment and the arrangement through the second interface by utilising a general process application protocol and a text file, respectively, adapted to the format of said data in the memory member of the process equipment.Type: GrantFiled: May 27, 2004Date of Patent: August 1, 2006Assignee: ABB ABInventors: Björn Andersson, Henrik Ryegård

Patent number: 6704800Abstract: The present invention provides a system and method to identify message sequences occurring in a computer or communication system. The present invention defines and detects undesirable sequence of messages, suppresses generation of undesirable sequences, and, if necessary, causes the termination of the execution of generating program module, or otherwise inhibiting the source of the undesirable message sequence. A report, indicating the messages generated as part of the undesirable message sequence and the generating program module and related information is provided. Message sequences transmitted to and from one program module to another program module may be tracked. In tracking messages, a starting message point may be set and all subsequent message transmittals may be included in a message depth and sequence depth count.Type: GrantFiled: October 7, 1999Date of Patent: March 9, 2004Assignee: Ericsson Inc.Inventors: Jangsik Lee, Bruce Rethwisch, Loita Jahnsson, Eric Turesson, Björn Andersson

Patent number: 6333733Abstract: A position-sensing unit for determining a relative position in one or more dimensions of two units. One or more position-sensing units can be used in a multidimensional pointer, such as a control lever, for controlling a position in up to six dimensions of, e.g., and object on a display. A position-sensing unit comprises a radiation source, a detector and a screen element arranged in the beam path for partial screening off of radiation. The radiation source and the detector comprise individual or separate fields for emitting or detecting radiation, in which case it is possible to distinguish radiation associated with one field from radiation associated with other fields. The determination of a position is carried out based on a comparison between the intensities of non-screened-off radiation associated with the different fields.Type: GrantFiled: March 2, 1999Date of Patent: December 25, 2001Assignee: Trioc ABInventors: Björn Andersson, Joakim Kvarnlöf, Bengt Andersson
